I stumbled around on others reviews of this product after i had already purchased it.
I was... nervous. I got cold feet in a way. Sat there starring at the horrifying words on my screen for a great while.
Almost cancelled my entire order.

Then i Waited Till it came, figuring i could return it if it was an issue.
It was intense to say the least.
The product got here.
I opened it.

AND THANK GOD!!!!!!
I didn't cancel.

I was amazed at how well it works and how easy it was to set up.
Even with a humidity and temp Thermostat.
I heard things about it not being built "heavy duty" enough for some people.
I'd have to disagree. But i did no such man handling with my installation process.
It work's better then i could have ever thought. I got my money worth, and i know you will.
BTW 14oo cfm was enough for my 28 foot Length by 11 foot wide space. You can use that for what it's worth when deciding if you should get the 3000 Cfm.

Moral of the whole thing.
They say people don't review enough and that it cause feedback issues.
and this is a problem.
But i say, If your going to do a review of an item.
Do it with truth and integrity. cause an item like this needs better reviews.

Fan works great and has an acceptable noise level, almost queit. The discharge dampers do not close tightly, they fall shut when the fan is switched off. A gusty breeze will cause them to flap open and shut. Next winter I will have to construct a way to seal off the dampers. I would prefer that the dampers close securely or they are provided with a way to dog them shut.

These are very poorly made, They have a cheap motor on them, fan shutters do not work properly. Right out of the box the shutters were damaged. Spend the extra cash and get a good one from graingers.

Great attic fan. sucks all the heat from my attic quick and doesn't make very much noise. it came quickly and the only problem i had with it is one of the shutters was bent a little but thats no problem...just bend it back and its in great condition! powerful fan! you do need to wire this one to a 120v source. (PLEASE NOTE) the fan blade is 14in long... the whole unit is around 20inx20in.

Great fan so far. Seems to be well made, was easy to install, works great with fairly low noise level. We are using it to ventilate a crawl space and so far so good. Would recommend this fan to anyone.

Shutters are terrible. Didn't notice unitl after contractor had already installed. Slight breeze from outside blows them open. Big gap on ends that doesn't allow shutters to seal off when not in use. Maybe OK for a chicken coup?

Bought the Ventamatic IF24 - 24" Heavy Duty Exhaust Fan at Tractor Supply. The fan looked interesting: 4100 CFM, energy efficient, and fully balanced.

First impressions, the fan was in the box and the bottom of the mounting frame was bent. Just minor sheet metal straightening, no major damage.

I installed the fan and turned it on. To my surprise, as the fan came up the full speed it started shaking so violently the internal braces started to bend. Removed the fan and will be taking the fan back to the store tomorrow to exchange. Hope the next one will be better.
